The characteristics of electric heating light oil blending compound technology is as follows (Li and Zhang 2005): Open image in new window Fig. 1 Wellbore structure of electric heating light oil blending compound technology (1) The construction is simple and special equipment is not needed; (2) High heating efficiency.
The construction of the near wellbore model involved creation of a high-resolution grid around the wellbore and perforations to capture detailed stress redistribution (Fig. 20).
A wellbore analysis presents several challenges regarding the drilling, construction and production phases.
And finally, based on the characteristics of shale gas horizontal wells, wellbore integrity control measures were proposed in terms of design and construction process, so as to improve the drilling quality (DQ).
Surge and swab pressures can be generated in different stages of well construction including tripping operations and reciprocation of drillstring in the wellbore.
Our synthetic case studies suggest that collection of a few tomographic profiles and interpretation of these profiles together with limited wellbore data can yield hydrological point values and spatial correlation structure information that can be used to aid numerical aquifer model construction, calibration, and flow simulation.
The Drilling & Evaluation segment provides field and reservoir modeling, drilling, evaluation, and wellbore placement solutions that enable customers to model, measure, and optimize their well construction activities.
Improper cement design can trigger well construction risks such as de-bonding and leakage pathways in near wellbore and through annulus.
Multidisciplinary methods (hydraulic tests and modelling, fluid sampling and modelling, analysis of cement and clay samples on the overcore) are used to get better insight, in a realistic wellbore context, on the interplay between the geochemical questions, and the operational and construction issues.
The dynamics of gas liquid mixtures in wellbores, degassing, and various flow rates, which are determined by the flow rate of wells and the construction of the lifting equipment, affect the balance of a salt solution.
